WebMASS RELATIONSHIPS IN CHEMICAL REACTIONS 3.5 (34.968 amu)(0.7553) + (36.956 amu)(0.2447) = 35.45 amu 3.6 Strategy: Each isotope contributes to the average atomic mass based on its relative abundance. Multiplying the mass of an isotope by its fractional abundance (not percent) will give the contribution to the WebChemists are concerned with mass relationships in chemical reactions, usually run on a macroscopic scale (grams, kilograms, etc.). To deal with the very large numbers of atoms and molecules in such samples, chemists developed the unit of the mole (abbreviated mol) and a unit of measure called the molar mass, which has units of g WebView full document. ____ 7.
